How much capacity do I need?
That depends on whether you want an emergency top-up or multiple recharges. Higher capacity almost always means more weight.

Power bank for iPhone Duo: what really matters
Capacity is only part of the story. USB-C PD, weight, form factor and reliable magnetic alignment matter just as much in daily use.
Balance capacity against weight
Large power banks offer more reserve but quickly become heavy. A smaller model can be better for daily carry, while larger capacity may make sense for travel.
- Support USB-C PD
- Provide appropriate output power
- Choose Qi2 only if magnetic charging is useful to you
- Check airline rules before flying
Cable or magnetic charging?
USB-C is efficient and often faster. Magnetic charging is more convenient but can create more heat and may charge more slowly depending on conditions.
Form factor matters with a foldable
A magnetic battery should not interfere with the hinge or make the device uncomfortable to hold. Compact designs are especially relevant here.

Frequently asked questions
Is Qi2 better than USB-C?
Not inherently. Qi2 is more convenient, while USB-C is usually more efficient. A power bank supporting both can be a practical compromise.
